Answer / lylez00

Because you're printing p, not *p. scanf takes addresses of
variables as arguments, but printf does not.

Answer / vignesh1988i

ya,, i think..
first we have declared an pointer variable *p and
assigned a value 20.... but we know that pointers are those
which can hold only the address of another variable..... so
surely in the memory P it wont have 20... so 20 will be
stored in some other unbknown variable in the memory which
wont be visible to user in thesr cases...... that unknown
memory address will be getting stored in this pointer
variable.... so when we give only p or *p it will print 20
and not the address of the unknown location containing
20........... because it will be directly accessible

Answer / immanuel

printf("%p",p); // this prints the address to 20

printf("%d",p); //this prints the value itself.

Answer / vignesh1988i

this will result in error.... pointer itself cant point to
any value... we, the users must make an explict assignment
for the pointer to point to an value .....
